HP-UX takes a very long time to boot and to be connected to

[Mawuse]

Hi,


I have just installed HP-UX v23 on four Itanium rx8620 servers.

The problem is that they take exagerately a very long time in the OS boot up process. " Starting Runner" takes about 45 minutes, (likewise Stopping Runner in the shutting down proccess); "Starting Mail Daemon" takes about 15 minutes likewise other services.

After the system is up and running, Telnet from a client machine takes 10 minutes before connecting. FTP from a client shows " connected to host" but never gives the ftp prompt : after 5 minutes, it will just show "connection closed by remote host".

Utilities like SWINSTALL; SWLIST takes up to 1 hour 30 minutes before launching the installation. I need help please, to get rid of all theses troubles. Your contributions are most welcome.

Thanks in advance for your prompt reply.



Regards,
Mawuse

I would look into name resolution issues. Try doing some nslookups to/from these machines and see how they work.

Hi,
have you checked your network setup? Is your DNS configuration correct ?

Start with an internal ping (by ip and name)
Progress onto a client ping (by ip and name)
Can you ping another server on same/other subnet?

Check your /etc/nsswitch.conf.

Please update with your findings.

Mawuse,

Two things, for the booting up problem make sure that you install the latest and greatest firmware for that box, for the loggin in problem, make sure that your resolution methods are set just fine in the machine, check your /etc/hosts file, /etc/nsswitch.conf and /etc/resolv.conf file.

Jaime.

Hi,

And also you just check with Syslog for any errors.

/var/adm/syslog/syslog.log

And check with DNS, NIS configurations are correctly configured. Whether that servers are reachable with this server in reasonable timings.

Mawuse,

I had slow boot times a while back and it was do to my NIS configuration. I turned it off for while before I had a chance to understand what was wrong. I eventually fixed my slow boot time.

It turns out that I had not set the following two things in my /etc/rc.config.d/namesvrs configuration file.

I had:
YPBIND_OPTIONS=""
YPSET_ADDR=""

I now have:
YPBIND_OPTIONS="-ypset"
YPSET_ADDR="xxx.xxx.xxx.xxx"

The YPSET_ADDR is the ip of the NIS server.

This may not be your problem, but it could be!

Good luck,
GBR

As mentioned, this is very likely DNS or NIS problems. The only way to fix it is to turn off DNS services (and if used, NIS) and use /etc/hosts as a temporary solution. Then fix your DNS and/or NIS server -- it is not working correctly and will severely impact all applications that need the network.

Hi All,

Thank you very much for your help.
I removed every DNS configuration from the unix servers and rebooted them. The systems took less than 3 minutes to come up. Right now, I am only relying on /etc/hosts until the stability of the DNS servers is tested.
Your contributions have saved a lot of hours even days for me.
